As the government announces further support for the UK's emerging graphene industry, James Baker from the National Graphene Institute says the emerging concept of a 'graphene city' can be a UK model for commercialising new scientific discoveries.

The nanostructures are coated in titanium oxide to which nitrogen has been added. This allows sunlight, rather than ultraviolet radiation, to trigger the process involving the chemical reaction and destruction of contaminants.

A new project at the National Physical Laboratory will develop methodologies to measure the radio-biological impact of gold nanoparticles, when used in combination with ionising radiation for enhancing radiotherapy treatments and medical imaging.

The microtiles are fabricated out of the superposition of two structural SU-8 layers featuring chiral copies of the same centro-symmetric pattern. They can coordinate laterally in water independently of their vertical orientation to form close-packed square lattice clusters.

Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics.

The ability to create conducting polymer films in a variety of shapes, thicknesses and surface properties rapidly and inexpensively will make growing and testing cells easier and more flexible, according to a team of Penn State bioengineers.

An international team of scientists has developed a new technique called rotational X-ray tracking (RXT). The researchers were successful in demonstrating the power of the new technique by using it to study small crystalline particles immobilized by the fact they form a colloidal gel under certain conditions.

Biomedical engineering researchers have developed a nanotechnology anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are inside a cancer cell, where they then combine to destroy the cell.

Researchers have developed a simple method for controlling the 'doping' of carbon nanotubes (CNTs), a chemical process that optimizes the tubes? properties. The method could improve the utility of doped CNTs in a number of nanotechnologies and flexible electronics, including CNT-silicon hybrid solar energy cells.

Scientists have shown for the first time the maximum theoretical limit of energy needed to control the magnetization of a single atom. The fundamental work can have great implications for the future of magnetic research and technology.
